Fundamentals of Video: Cameras and Shooting


http://www.lynda.com/tutorial/97394

Video Format HD use 1920x1080

Frame Rate

24 30 or 25: 24 is film quality
50 and 60 are for slow motion

Progressive is like film; interlace is for broadcast.

Focus
1. use bigger monitor
2. use focus assist
3. peaking
* always zoom-in, then focus, then zoom-out
* use mannual focus in most cases

Neutral Density (ND) filter

Shutter speed
• the longer the shutter speed, the more motion blurer, the more light coming in the picture
• normal shutter speed: double the frame rate, such as 24fps with 1/48 shutter speed. we can also go one or two stops lower such as 1/32

White balance - don't forget

Gain generates noise.

Camera move: zoom, pan, tilt (sometimes use auto focus)

Five sound rules
1. get the microphone close to the subject
2. always use headset
3. monitor levels from the camera
4. scout locations for sound
5. record room tone

Fine sound zone: -20 db to -12db
